# Advanced PHP 7 eCommerce Website (https://22digital.co.za)
#
# (!) Using `.htaccess` files slows down Apache, therefore, if you have
# access to the main server configuration file (which is usually called
# `httpd.conf`), you should add this logic there and delete whatever is not
# relevant below.
